1. d4 Nf6 2. e3 d5 3. Bd3 e6 4. f4 { Not a great opening, but a good anti computer style. } c5 5. c3 Bd6 6. Nf3 O-O 7. O-O c4 8. Bc2 b5 9. Bd2 Qb6 10. Be1 Nc6 11. Bh4 b4 12. Bxf6 gxf6 13. e4!? { I'm sacking the a1 rook for the attack. } bxc3 14. bxc3 Qb2 15. e5 Bc7 16. exf6 Bxf4 17. Ne5 Nxe5 18. dxe5 Bh6 { At this point I considered the game an easy win, but the silicon beast finds counterplay. } 19. Rf2 Qxa1 20. Qh5 Rb8 21. Rf1 Be3+ 22. Kh1 h6 23. Qg4+ Bg5 24. h4 Qxa2! { Now is a critical moment. The black queen threatens to come to c2 and g6. } 25. Be4!! { I don't remember ever doing a sac like this. The whole point is, that the pawn will block queen from protecting g6. } dxe4 26. hxg5 h5 27. Qxh5 Qe2 { And here is the human weakness. I forgot, that when a mate is coming, the silicon will sacrifice anything to prolong the game. I simply thought, that it had found a refutation, and quickly tried the last chance of a blockade. } 28. Rf3?? Rxb1+ 29. Kh2 exf3 0-1 [/pgn]
